So, I decided to start another scooter project. Yesterday, I purchased one dead 150cc 2008 JMStar scooter and an extra 150cc engine for $200. The guy had about 5 dead scooters as projects, and was selling them off.
On the dead scooter: all the body panels are there, has new tires, has new battery. The guy said that he "the piston had a hole in it, so I rebuilt the top end, but it is blowing oil so the rings haven't seated properly, probably needs new rings". I think he was blowing smoke up my behind, but that really did not matter. Clearly he had done some stuff to it, but I don't think he ever started this thing.
Cosmetically, the thing needs new mirrors. In the engine compartment, it looks like a cyclone hit it. Clearly the emissions have been ripped out and stuff plugged haphazardly. There is no air filter/air box. The tubes to the vacuum petcock are not secured and barely hanging on. There is no lock for the seat, and there is a hole around the where the ignition key is. When I turn the ignition and try to start the engine, I get nothing. No lights, no horn, nostarter click.. nothing.
So, if YOU had a scooter like this, where would you begin?
I am tempted to start with an ignition and new locks. move to put an air filter on there, re-plumb with new fuel and vacuum tubing, and then start working out the electrical problems. Once I achieve any kind of spark, then try to get it started. Maybe put a new top end assembly. What do you think? How would you tackle this dead scooter? Is there any way I can tell if he put a new top end on it? What are the chances that the crank/bearings are bad? Would you pull the engine to work on it? (most panels are off).

fuel pump

things are too cheap to screw around with it very long. If its the original fuel pump, you want to replace it anyway. Why not get a mikuni or an electric fuel pump for $25? It does two things... removes this as the issue for this problem, and gets rid of a future problem with a quality replacement.
I'd only consider a manual petcock if it was EASY to get to and operate with winter gloved hands.

If you really are done with it I'm always up for a challenge you're over in coconut creek right? I live in pompano There you go. That's the easiest way to get a lot of knowledge and learn a lot of the tricks of the trade fast. |

i don't have the skills to deal with carb and/or electrical issues. You underestimate yourself. You do have the skill. When I get to the point where you are at, I look at it this way: its fracked up. If you are going to sell it with a fracked up carb, why not learn something from it and take the thing off and follow a you tube video and learn something. You can't frack it up any more than it already is. As for a multimeter, they are $5 at harbor freight. All you need to know is where the voltage setting is on the dial. Even if you reverse polarity, you will simply be reading negative magnitude values. And they are irreplaceable for finding shorts. you put it on the ohm scale and look for zero. You DO have the skills, you just don't know how to formulate a plan to troubleshoot. Just about anything you need to replace on a scooter is $25. You can do anything that is plug-n-play. All it takes is a wrench. You can do this. Even cleaning a carb is not that much more advanced than a jigsaw puzzle. |

So it is pretty rare. BTW that Bintelli Havoc is a nice scoot. If I was purchasing new, I'd definitely go for one of those.

umm... I should have clarified "dual disc". I mean disc on front and rear, rather than two discs on front like many motorcycles. See, I like dual discs. But I noticed in another thread that the engine/transmission is diff from disc on the rear vs. drum on the rear. I also notice that there are very few scoots with disc on the rear.

I have been looking for another scooter project to lend a riding buddy (wife/brother/anyone who will get a license and ride with me). So I was looking for a scoot similar to mine: 13" wheels, dual disc brakes, 150cc. But I noticed that dual disc brakes with 13" wheels is somewhat rare even when purchasing new. What's up with that? Was I just lucky (or not) when I purchased this configuration?

Still working on all of my reliability upgrades... getting rid of the original vacuum operated fuel pump, changing some bulbs to LED, adjust valves, fix kick start (that I somehow broke when I changed to a gates belt).

So, after putting 200 miles on learning to ride and getting my license, I made my first utilitarian "instead of" trip today. I took the scoot, instead of the car, on a typical trip to the store. I rode 8 miles to get there and 8 miles back.

I removed in EGR valve and evaporative system and there was no drain hose to deal with.

woohoo! I put 60 miles on the scooter this morning in a trek to the GA dept of driver services and got my motorcycle license!
The ride in was soup. No one ever warned me about fog! I had quarter mile visibility but both the inside and outside of my helmet kept fogging over. My jacket is a fireman's jacket surplussed from a local station. it held up really well... not waterproof but definitely water resistant enough for me to stay dry. I got there and then waited on the course for about 20 minutes for the examiner to come. In that time, I was able to practice the course about 4 times. Before going in I was really worried as I only had about 135 miles/1 month worth of practice. But it was no problem at all. By the time that I finished, the fog had burned off and the sun was shining, temp was above 60F, and I had a motorcycle license. While I took the direct 23.3 mile route there, I took the scenic 38 mile ride home. Across a mountain (and the aptly named "Mountain Road") and through the country. Sweet!

battery on tender. Tomorrow, I will be making my longest trip ever (23 miles each way) to the DMV to take my motorcycle test.

I am looking to purchase a second 150cc scooter, and there is one locally in a CL ad for $150... a Qlink. It is my understanding that this has a 1P58MJ water cooled engine. Should I seriously look at this scoot (the price is right for a new project) or should I pass and stick looking for a 150cc gy6-based scooter?

From his first post and the pics of the bike, I'd estimate that he wandered on a good deal and is just trying to get it started and was either told this or just doesn't know. There's an "idle screw" and a "starter solenoid" but better question is "what does it do when you try to start it?".
